docker-compose(grafana influxdb) + telegraf 快速搭建简单监控

灵活实现方案：

1: telegraf 为go 语言写得占用内存小收集主机各项监控数据定时写入时序DB influxdb ------------------------"telegraf + influxdb + grafana"

2：也可自已用python 编写监控脚本收集主机各项数据写入 influxdb ------------------------------------------------------- "python + influxdb + grafana"

我们选第一种：第二种我也试了重点在python data-type 上 int string 写入 influxdb db 时要注意

#主机清单说明

172.16.1.6 #安装 telegraf 并设置配置文件收集系统各项监控数据然后写入远程主机（172.16.1.50） influxdb 内

172.16.1.50 #安装 docker , docker-compose 运行start-DockerCompose_grafana.sh 生成docker-compose_grafana.yml 并运行

特别说明:

#1， 172.16.1.50运行 docker-compose 会去docker-hub 拉取最新得 grafana images 镜像所以必须创建 grafana 用户组

#2，grafana 镜像从4.1.2 以后容器内都是以普通用户运行更换低版镜像并不需要在宿主机上创建grafana user 会在当前目录下生成 docker-compose-grafana.yml docker-compose file

#172.16.1.50主机必须条件 , docker , docker-compose

运行start-DockerCompose_grafana.sh 生成docker-compose_grafana.yml 并自动运行： docker-compose -f docker-compose_grafana.yml up -d

cat start-DockerCompose_grafana.sh

#!/bin/bash
GRAFANA_DIR=/grafana-dir
GRAFANA_plugins=/plugins

INSPECT_ID=`id 472 >> /dev/null 2>&1 `
INSPECT_FILE=`-f ./docker-compose_grafana.yml >> /dev/null 2>&1`

function newfile () {
cat >> ./docker-compose_grafana.yml <<EOF

2： 172.16.1.6 agent 安装 telegraf 并设置配置文件

2.1下载

wget http://get.influxdb.org/telegraf/telegraf-0.11.1-1.x86_64.rpm

2、2安装

yum localinstall telegraf-0.11.1-1.x86_64.rpm -y

2.3修改配置文件：

cat /etc/telegraf/telegrag.conf #扩展目录 /etc/telegraf/telegrag.d/[global_tags]

[global_tags]
[agent]
  interval = "8s"
  round_interval = true
  metric_batch_size = 1000
  metric_buffer_limit = 10000
  collection_jitter = "0s"
  flush_interval = "10s"
  flush_jitter = "0s"
  precision = ""
  debug = false
  quiet = false
  logfile = ""
  hostname = ""
  omit_hostname = false
[[outputs.influxdb]]
urls = ["http://172.16.1.50:8086"]
database = "telegraf"
  retention_policy = ""
  write_consistency = "any"
  timeout = "5s"
   username = "root"
  password = "237356573"
[[inputs.net]]
interfaces = ["ens33"]
[[inputs.cpu]]
  percpu = true
  totalcpu = true
  collect_cpu_time = false
  report_active = false
